Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00104 | $0.00553 |
| Opus 5 | $0.00052 | $0.00277 |
| Sonnet 5 | $0.00021 | $0.00111 |
| Haiku 4.5 | $0.00010 | $0.00055 |
Grade A, and why
vrc-udon-networking-rules scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
VRC Udon Networking Rules
役割
VRChat UdonSharp のネットワーク挙動を、実装前に docs/NETWORKING_RULES.md として固定する。誰が状態を持つか、何を同期するか、何をイベントで流すか、Late Joiner をどう扱うかを先に決める。
この Skill を使う場面
- synced variable を使う
SendCustomNetworkEventを使う- Ownership の移譲や検証がある
- Late Joiner 対応が必要
- Player Data や Player Object を含むネットワーク仕様を project-owned 文書へ固定したい
この Skill を使わない場面
- 保存方式だけを選びたい場合:
vrc-udon-persistence-sync - UI や操作導線だけを設計したい場合:
vrc-udon-ui-menu
進め方
references/networking-guide.mdを読む。- 導入先に networking ルール文書が無ければ
assets/templates/docs/NETWORKING_RULES.mdを配置する。 - 仕様を次の順で埋める。
- 状態正本
- イベント
- Ownership
- Late Joiner
- Persistence を含む復元順
- 実装前に
docs/NETWORKING_RULES.mdを確定する。
担当範囲
- Network Event と同期変数の役割分離
- Ownership の固定
- Late Joiner 前提の仕様化
- networking 文書雛形の配布
注意点
- 一時イベントと持続状態を混ぜない
- 誰が最終状態を確定するかを 1 箇所に寄せる
- Persistence は in-instance sync の代替ではない
- 公式根拠が薄い挙動は断定しない
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

vrc-udon-networking-rules is a skill published in the GitHub repository sechiro/VRCUdonSkills-for-Codex (58 stars, last pushed 4mo ago), licensed MIT. It adds 104 tokens to every session and 553 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
gameobject-component-destroy
Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components first.
unity-version-split
Split a C# file into Unity 6.5+ and pre-Unity 6.5 variants. Use when a file needs different implementations for different Unity versions due to API changes (e.g., EntityId vs int, GetEntityId vs GetInstanceID).
godot-signals-groups
Build event-driven, decoupled Godot 4.7 gameplay with signals and node groups: declare and emit custom signals, connect with Callables (incl. bind/one-shot), and broadcast to many nodes via groups and callgroup. Use when wiring node communication in a Godot project, replacing tight references with signals…
unity-addressables
Manage Addressables groups, entries, profiles and content builds (com.unity.addressables, reflection-based).
motion
How an agent turns a character mesh into a usable animated FBX — and how to judge whether the result is shippable.
playtest-report
Generates a structured playtest report template or analyzes existing playtest notes into a structured format. Use this to standardize playtest feedback collection and analysis.
